Curving pier - San Francisco, CA
This pier is on the north end of the San Francisco peninsula in San Francisco Maritime National Historical Park. The curving pier creates a breakwater area that shelters a little marina called the Aquatic Park Cove. From that pier a visitor can look Eastward and see the vessels docked at the Maritime Museum, southward to see the Ghirardelli chocolate store, northward towards Marin County Headlands, and Westward to the Golden Gate.
The National Park Service has a great aerial shot:
